2013 PORSCHE 911 TARGA4 traction control

2726
The interior of a 9 11 doesn’t follow
a particular fashion. It follows clear
principles.
Principles which also apply to the
new 9 11 Targa 4 models. Here, the
predominantly sporty interior design is
successfully combined with a classic

layout and high-quality equipment.
There are no distractions, no gadgets;
every thing is focused on the driver and
on driving. This is the only way of
creating what you could call a sport y
st yle – you could even say it ’s the
very art of sports car design.
These principles are expressed in
practice by the ascending centre
console. Its sophisticated ergonomic
design utilises a clear operating logic
for its controls, such as those for the
individually adjustable two-zone air
conditioning system or for operating
the roof.
Sporty. Classic. Elegant.
It’s wonderful when all styles unite in harmony.

Sports car aesthetes will love this topic.
Because it ’s all about curves. And sport.
And the enhanced Porsche Traction
Management (PTM) is in control of both.
Fit ted as standard, PTM is an active all-
wheel-drive system with an electronically
variable map-controlled multi-plate clutch,
automatic brake differential (ABD) and
anti-slip regulation (ASR). Drive power is distributed bet ween the
permanently driven rear axle and the
front axle by means of the electronically
variable multi-plate clutch. The status of
the vehicle is continuously monitored so
that it is possible to respond to different
driving situations. Sensors are used to
collect a range of data, including the
rotational speed of all four wheels, the
lateral and longitudinal acceleration of
the car and the current steering angle. If, for example, the rear wheels begin to
lose traction under acceleration, a greater
proportion of the drive power is automat -
ically transmit ted to the front axle by
a more positive engagement of the multi-
plate clutch. In addition, ASR prevents
wheel spin by adapting the engine’s power
output. During cornering, the optimal
level of drive power is distributed to the
front wheels to ensure excellent lateral
stability. In conjunction with
Porsche Stability
Management (PSM), PTM helps to ensure
the perfect distribution of drive power for
optimum traction in most road scenarios,
whether on long straights, through tight
corners, or on surfaces with different
friction coefficients.
There’s one thing that unites engineering and design:
an extraordinary fascination for curves.

Dynamic engine mounts.
The dynamic engine mounts are included
as part of the Sport Chrono Package. The
electronically controlled system minimises
the oscillations and vibrations of the entire
drivetrain, especially the engine, and
combines the benefits of a hard or soft
engine mounting arrangement.
The stiffness and damping properties
of the engine mounts are adapted to
changes in driving st yle and road surface
conditions. Handling is noticeably more
stable under load change conditions and
in fast corners. Whenever a less asser -
tive driving st yle is adopted, the dynamic
engine mounts provide a greater level
of comfort.
Wheels.
The 9 11 Targa 4 is equipped with 19-inch
wheels as standard. These are light-
weight alloys featuring a classic sport y
design. Tyre sizes are 235/40 ZR 19

and 295/35 ZR 19 at the front and rear,
respectively.
For fuel consumption and CO
2 emissions, please refer to page 103. The S model is equipped with light-alloy
20-inch wheels as standard. The visual
effect is sport y and dynamic.
The large t yre size improves both ride
comfort and track performance. Rolling
resistance, dry braking distances and
t yre weight are all comparatively low.
Porsche Stability Management (PSM).
As standard, the new 9 11 Targa 4 models
are equipped with
Porsche Stability
Management (PSM) which maintains
stabilit y even at the limits of dynamic
driving performance.
Sensors continuously monitor the direc -
tion, speed, yaw velocit y and lateral
acceleration of the car. PSM uses this
information to calculate the actual

direction of travel at any given moment. If
the car begins to oversteer or under -
steer, PSM applies selective braking on
individual wheels to restore stability.

Under acceleration on wet or low-grip road
surfaces, PSM improves traction using
the automatic brake differential (ABD) and
anti-slip regulation (ASR). The result is a
high level of driving stabilit y and safet y
combined with extraordinary agility.
Porsche Torque Vectoring (PTV and
PTV Plus).
PTV in conjunction with the manual
gearbox, or PT V Plus with Porsche
Doppelkupplung (PDK), are available as
options for the new 911 Targa 4 and
are standard on the new 9 11 Targa 4S.
Both systems actively enhance vehicle
dynamics and stabilit y by braking the
rear wheels as the situation demands.
In addition, a mechanical (PT V) or elec -
tronic (PT V Plus) rear-axle differential
lock is responsible for infinitely variable
torque distribution.
When the car is driven assertively into
a corner, moderate brake pressure is
applied to the inside rear wheel. Conse -
quently, a greater amount of drive force is distributed to the outside rear wheel,
inducing an additional rotational pulse
(yaw moment) around the vehicle’s

vertical axis. This results in a direct and
sport y steering action as the car enters
the corner.
At low and medium vehicle speeds, PT V
and PT V Plus significantly increase agilit y
and steering precision. At high speeds
and when accelerating out of corners,
the rear differential lock ensures greater
driving stability. Whichever system is
fitted, it interacts with Porsche Stability
Management (PSM) to improve driving stabilit y on a range of surface conditions,
including the wet and snow.
